		+	Now write:
		+
		+	iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
		+
		+	What this does is make a NAT rule for post-routing. It sets the eth0 as the output card (The one out to the internet) and sets source to it's own IP through MASQUERADE. Then write:
		+
		+	echo 1 > /proc/sys/net/ipv4/ip_forward
		+
		+	This will enable it without a reboot.
		+
		+	Just to be sure, save it.
		+
		+	iptables-save > /etc/iptables.rules
		+
		+	Now that it’s saved we need to load the iptables.rules on starting the network:
		+
		+	vi /etc/network/interfaces
		+
		+	# The extended interfaces
		+	auto eth0
		+	iface eth0 inet dhcp

		+	To make it only listen to one ethernet, you will have to edit '''/etc/default/dhcp3-server''' to specify. It's pretty straightforward:
		+
		+	INTERFACES="eth1"
		+
		+	or any other number, depending on your hardware setup.
		+
		+	Then to configure it, you will have to edit '''/etc/dhcp3/dhcpd.conf'''. It is already preconfigured to some extend but you will need to uncomment certain things first. This is essentially what I changed:
		+
		+	# Sample /etc/dhcpd.conf
		+	# (add your comments here)
		+	default-lease-time 600;
		+	max-lease-time 7200;
		+	option subnet-mask 255.255.255.0;

		+	option domain-name-servers 192.168.166.1;
		+	option domain-name "trillex.dk";
		+	subnet 192.168.166.0 netmask 255.255.255.0 {
		+	range 192.168.1.10 192.168.1.254;

		+
		+	The reason I cannot see or use my own domain, is because the IP I've used, does not exist. Yet!
		+
		+	So we need to make it start up and work. This is done through the '''/etc/network/interfaces''' file.
		+
		+	sudo vi /etc/network/interfaces
		+
		+	At the buttom, enter this:
		+
		+	# The secondary network interface
		+	auto eth1
		+	iface eth1 inet static
		+	address 192.168.166.1
		+	netmask 255.255.255.0
		+
		+	Reboot the server, just to check that everything works out.
		+
		+	Now try and type
		+
		+	dig trillex.dk
		+
		+	It works!
